This paper presents the outcome of the bibliometrics analysis of research sourced from the Web of Science collection. A research evolution, hotspots of peer instruction, and potential topics using bibliometrics to visualize related research from 1971 to 2022 was conducted, using CiteSpace to analyze keywords co-occurrence, time zone, burst detection and strategic diagram. Six themes emerged: competence, technology, outcome, participation, students' ability, and others. Among them, benefits to students, such as improving students' ability, confidence, and learning performance are the hotspots. Teachers' perspectives, exploration of the implementation model, students' attitudes, motivation, demands, and cognition are potential topics for future research.
